343 industries is making the new saga which will be at least a trilogy.

At the end of Halo 3, Master Chief and Cortana are sent adrift into deep space. After beating the game on Legendary, you see a preview of a planet they are drifting towards. That planet is Requiem, a vast and diverse land that Master Chief and Cortana end up crash landing on.

In Halo 4 we’ll finally meet an entirely new class of enemy, a species called the Prometheans. They work together against you. A Promethean Knight that you have to face may spawn Watchers to shield and defend them, plus watchers can summon Crawlers and even resurrect the Promethean Knight.

Crawlers are manageable one on one but they’re tough in numbers…

I like the HUD changes I’ve seen so far. They’re more realistic with a contoured display and a perception of depth as if your looking out of a helmet… But crosshairs are way off, maybe its just the demo and the developers are working it out, but so far rounds are hitting enemies way left of your targets…

We’ll have lots of new weapons and abilities including the Light Rifle and Scattergun that look great. And supposedly you’ll be able to use a secondary device like a smart phone or tablet to view weapons schematics and other new features while you play.

In multiplayer you can create your own Spartan and play different modes.
